--- Comment #4 from Tony Ye <tony.ye at intel.com> ---
Tvrtko, the VME sampler cannot be accessed in a simple batch. You need to
prepare some states, surfaces, and then launch a kernel to do something with
VME. It's similar to
https://cgit.freedesktop.org/xorg/app/intel-gpu-tools/tree/lib/media_fill.c,
but more efforts are required. Unfortunately, I do not have something which is
already working to share with you.

The simplest way to reproduce the issue to use the media driver to encode a
stream.
